group formation and auto repair

[Beso]

it would be awesome for units to stick to a formation where supports and anti air stay in the back do there thing and go back to be protected by heavier units
clicking shift+R to fix every thing
and super super units are always nice specially carriers !

You can also ALT+Click to force unit formation.

Yes, i wished my squishy units would stay at the back always.

Thats where your control groups come in, have those units under different control groups and position them exactly where you want them
